CHURN.

known that We. LESTER E. MARSH and LAWRENCE E. MARSH, citizens'of the;United States. residing at Black Lick, vin the count-y of Indiana andState of Pezmsylvania. have invented certain newand useful Improvemen-tsinl (Thnx-ns, of which the following is a specification, referenceheilig had therein tothe accompanying drawing. e l n This inventionrelates to ehurns, and the.

vprincipal object ofthe same is to provide a novel arrangement offlashers therefor and means for `rotating thesalne in oppositedirections.`r j

' In carrying out the objects of the invention lgenerally stated aboveit will he understood, of course, that the essential features thereofareneressarily susceptible of changes view of a -churn constructed inaccordance `with this invention. Fig. 2 is a transverse A sectional viewthereof tali-en on the line 2 2,

Fig. l. Fig. 3 isa fragmentary detail per- 1 spertivrview of thedashers. Fig'. 4 is a de- 1s provided with supporting legs 2 and with valoiver drain outlet 3that is normally seal ed by a plug 4. The uppersurface of the bottom of saidreceptacle is provided with a central platehaving a central bearing y6 formed thereln. kA supportingledge 1scarried by the upper portion of the inner surface of receptacle 1.External'ly, the upper end of receptacle 1 is provided with oppositelydisposed lugs S each having a screw 9 pivotally mounted therein andwhich carries a clamping nut l0. Y

The churn. is provided with inner and outer dashcrs, the outer dashercomposed of a horizontal base bar 11 provided with a wear plate 12 andacentral pivot stud 13 which projects above andy below said bar.l Thelower portionof said stud .is journaleii in bearing 6 of plate 5.Agitating bars i4 project fromfthe ends of bar 5, the upper ends oi bars14 being connected by a horizontal g Specification of Letters Patent.Application ledMay 7, 1910.

is formed. The inner dasher is composed of a horizontalbase bar 17provided with a .bottom plate 18 in which a central"bearingV upper endsof'said bars 20 being connected by a horizontal bar 21. Said bar 21 hasa plate 22 centrally located on its upper surface which is providedlwith va squared opening 23. The inner dasberis smaller than ther outerdasher and is freely rotatable therein- A supporting bar 24 extendsacross the upper end. of receptacle 1, the ends of said bar beingprovided vwith slots 25 which-are j UNITED srATEs rATENroFFioE.

bar 15 through which a centralopening 16 engaged `by the screws 9 anddetachably clamped to the top vof receptacle 1 by the nuts 10. Said baris provided with a central sleeve 26. one'portion of which isiin theforni of a hingedlateh 27 that may be I locked to the said bar 24 bymeans of the embracing clip 2S' and set screw 29. y

A tubular shaft 30 extends through sleever 2G and has a flange 3l at itslower end that is bolted or otherwise rigidly but detachably fastened toupper bar 15 of the outer dasher. The projected upper portion of shaft30 has a gear ivheel 32- rigidly but detaehably fastened thereon bvmains of a set screw 33, said gear being in mesh with the lower portionof a gear 34 carried by one end of a shaft 3.3 tliatV ismounted inbearings 3G at they upper end lof a standard 37 projecting' fromsupporting bar 24. .A c-ranlthandle 38 is carried by shaft 35.k tofacilitate manual rotation of said shaft.v

- A sha Ft 39 projects throughtubular shaft 30, the upper end of whchkisprovidedv with a gear wheel 40 that is in mesh with the upper portion ofgear 34. Shaft 39 has an enlarged ylower portion 41 that;k is 'yrotatable within shaft 30, antifriction bear- Y y ing 42 beinginterposed between the said' en-V larged lower portion 41 and shaft 30.lSaid enlarged portion 41 projects through opening 16 of dasher bar 15and terminates in a reduced .squared extension 43 that is tted v withinoi'iening 23 of plate 22 oy dasher bar 21. Saidshaft 39 carries anadjustable collar -44 which clamps la platel 45 over the open upper endof tubular shaft 30.

A spring 46 is coiled about shaft 39 Within tubular sliat30', one end ofsaid spring bearing against the upper :portion of en-Y '.largement 41 ofshaft 39, the other end of i said spring bearin against` plate 45.k As

will be obvious, sai spring is constantly exertinff a pressure on shaft39 tending to retain vits squared extension 43 in engage ment withopening 23. p

A cover is provided for the churn, said cover being formed of duplicatesections 47 which are seated on ledge 7.

It will be seen from the foregoing that by rotating shaft 35, the innerand outer dashers will` be rotated in opposite direc` tions. It willalso kbe seen that by releasing supporting bar 24 fromtreceptacle 1, the

entire operating mechanism may be removed from the receptacle, and alsothat by releasing collar 44, shaft 39 may be released'fron'r the innerdasher and removed from shaft 39, vwhich permits access to be readilyhad to all parts of the churn so that theyA may be thoroughly cleaned.Y,

That we claim as our 1nvent1o1L1s:-V

l. A churn comprising a receptacle, inner n Land outer dashers rotatablymounted therein, a supporting bar carried by the upper end of saidreceptacle, a tubular shaft journaled in said bar and engaging the outerdashers, a second shaftl extending through the tubular shaft, saidsecond shaftengaging the inner dashers and provided with an enlargedportion, a.A plate carried by the tubular shaft, al spring on saidsecond shaft and interposed between said plate and the enlarged portionof said shaft, and meansA engaging the inner` dasher, means lfor yieldvl ably holding said shaft in engagement with said inner dasher, andmeans for rotating vsaid shafts 1n an opposite dlrectlon;

`3. A churn comprising a receptacle, inner and outer dashers rotatabletherein, a tubular shaft connected to one of said dashers, a

shaft extending through saidtubular shaftv and engaging the otherdasher, a spring carried by the last-mentloned shaft for nor- -mallyholding the same in engagement.I with its dasher, and means for rotatingsaid shafts 1n an opposite dlrectlon. f 1

4. A churn comprising a receptaclemmer and outer dashers rotatablymounted therein, a support carried by saidy receptacle, a tubular shaft)ournaled therein and engagu n mg the outer dashers, a second shaftextending through the tubularfshaft and rotatable therein, said secondshaft engaging the inner dashers, 'means exerting a pressure on the.second shaft to retain the same in engage- 'ment with the innerdashers, and means for rotating said shafts in an opposite direction.

A churn comprising a receptacle, oppoksiteiy disposed screws pivotallyconnected to the upper end thereof, dashers for saidy y receptacle, asupporting bar extending acrossl -the top of said receptacle andprovided with.l slotted ends for the reception of said screws,

dasher-operatiug mechanism carried by said j f bar, andl clamping nutscarried by said screws for detachably fastening said bars to saidreceptacle. v

In testimony whereof We hereunto aiiix n our signatures in presence oftwo witnesses.
